vocalization
possible functions of the sinuses include: 1. air conditioning 2. pressure damping 3. reduction of skull weight 4. heat insulation 5. flotation of skull in water 6. increasing the olfactory area 7. mechanical rigidity 8. vocal resonance and diminution of auditory feedback 9 There are four pairs sinuses, the maxillary is largest, then frontal ,ethmoidal and sphenoidal is ( below eye sockets) is to provide mucous and act as a resonance chamber for sound +lighten weight of the skull. 10. mucous glands moisten the air ciculating between the conchae, if fluid does not drain , this causes sinuses headache.
